"PA" equipotential bonding. When transmitter ME2 is connected
to flowmeter sensor MS26, transmitter ME2 also has to be
connected to "PA".
Important
An additional document with Ex safety instructions is available for measuring systems that are
used in explosion hazardous areas (Applies to FM / CSA only).
As a result, it is crucial that the specifications and data it lists are also observed.
